Multi-purpose sensors able to take both blood and sweat measurements would offer a broad-spectrum overview of the wearer’s health.
Though wearable health monitors have become more common, they are limited in their information and accuracy. To offer a more detailed overview from wearables, the team from KTH created multi-purpose electrochemical sensors able to take readings from both sweat and blood. The sensors can be embedded in a patch, woven into clothing or deployed as microneedles, where they will gather their samples and transmit the data to a paired app.
According to the team, the wider range of information gathered could be valuable to athletes avoiding dehydration as well as patients suffering from renal failure from kidney disease.
